 Test that accessing to invalid changelog cache is avoided at
 subsequent operations even if repo object is reused even after failure
 of transaction (see 0a7610758c42 also)
 
 "hg log" after failure of transaction is needed to detect invalid
 cache in repoview: this can't detect by "hg verify" only.
 
 Combination of "finalization" and "empty-ness of changelog" (2 x 2 =
 4) are tested, because '00changelog.i' are differently changed in each
 cases.
